Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity on page 3 of the PDF, learners discover how science and Halloween are fun companions as they make paper bleed.

In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

In this activity, learners will explore acid-base reactions and create their own bubbly results.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.
